The Inverse Head and Shoulders Set-Up
Three lows with the middle one deepest, two rallies between them forming a neckline, and the break of that neckline as the confirmation.
MadStockAlerts Research · Updated September 4, 2026
What to take away
- The head is the lowest point and the shoulders should be roughly level with each other.
- The neckline is drawn across the two rallies between the lows, and it usually slopes.
- The right shoulder forming on the lightest volume of the three is the core evidence.
- It is the most widely recognised reversal shape, which is exactly why the false break is so common.
- The measured objective adds the head-to-neckline distance to the break.

The shoulder that does not reach the head
The most recognised reversal shape, and the one claim inside it that actually does the work. Plus why its published success rates are the least trustworthy in the field.
This lesson is part of a Stock Alerts + Tools plan.
The shape
A decline makes a low, rallies, makes a deeper low, rallies again to roughly the previous rally's level, and then makes a third low that is higher than the middle one. Three lows, the middle deepest, and a line drawn across the two intervening highs.
The neckline is rarely horizontal and the slope is informative. An upward-sloping neckline means each rally is stopping higher, which is the shape confirming itself; one sloping steeply downward means each rally is weaker, and a pattern whose neckline falls away is describing something that has not really turned.
- Three lows, the middle one clearly deepest, with the outer two roughly level.
- Two rallies between them reaching similar prices, so a neckline can be drawn.
- Volume heaviest at the head or the left shoulder and lightest at the right.
- A real decline into the pattern, of months rather than weeks.

Why it forms
The three lows are three separate attempts to sell the market down and one of them going too far. The head is capitulation — the point at which the last people who were going to panic did — and its depth relative to the shoulders is a rough measure of how complete that was.
The right shoulder is where the pattern earns its reputation. Price falls again, but stops well above the head, on the lightest volume of the three lows. The reading is that the sellers who produced the head are gone: the same conditions no longer produce the same decline, and that is a change in the market's supply rather than in its mood.
The right shoulder failing to reach the head is the whole argument. Everything else in the structure is context. If the third low undercuts the middle one there is no pattern, regardless of how good the first two-thirds of the drawing looked, and no amount of neckline geometry recovers it.
| What to look at | Set-up intact | Set-up failing |
|---|---|---|
| The right shoulder | Clearly higher than the head | At or below the head |
| Volume across the three lows | Lightest at the right shoulder | Heaviest at the right shoulder |
| The neckline | Flat or rising | Falling steeply away |
The price points that define it
A set-up is a shape plus a handful of prices. The shape is what makes it recognisable; the prices are what make it something that can be measured, reviewed afterwards and argued about honestly. These are the levels this one is read from.
| Level | Where it sits | What it tells you |
|---|---|---|
| The neckline | Drawn across the two rallies between the lows | The reference the set-up completes through. Because it usually slopes, the level has to be re-read rather than remembered. |
| The head | The deepest of the three lows | The floor of the structure and the base of the measurement. Below it the pattern has failed outright. |
| The right shoulder low | The third and highest of the lows | Where the reading stops holding for most conventions, since it is the last price at which the pattern's central claim was still true. |
| The head-to-neckline distance | Measured vertically at the head | What the measured objective is scaled to, projected up from wherever the neckline is broken. |
Where the set-up completes
- 1The triggerThe set-up completes on a close above the neckline, measured at the bar where the break happens rather than where the line was first drawn. Volume expanding on the break is the standard confirmation, and it matters more here than in most shapes because the pattern is so widely watched that a break without participation usually means the participation went elsewhere.
- 2Where the reading stops holdingThe reading stops holding below the right shoulder's low. Falling below the head is the outright failure, but by then the structure has been gone for some time; the shoulder is the level that carries the pattern's actual claim.
- 3The measured objectiveThe conventional measured objective takes the vertical distance from the head to the neckline and projects it upward from the break. It is the standard convention for this shape and it produces large numbers for deep patterns, with the usual caveat that the objective is reached far less often than the break follows through.
- 4Through the moveThe convention expects a pullback to the neckline after the break, and treats the neckline holding as support as the confirmation the shape offers. A break followed immediately by a close back under the line is the beginning of the failure case rather than an ordinary retest.
Each of these describes where a convention puts a level, not what anybody should do at it. Whether a level is worth acting on at all is a question about position size, cost and the rest of a plan, and the answer differs for every account.
How often it follows through
The band assumes the full construction and a break on real volume. This is the most-quoted reversal pattern in the literature and its published rates are the most inflated, precisely because a three-low structure that failed is never recorded as having been one.
Read that as a floor rather than an expectation. A set-up that follows through two times in three still leaves one in three that does not, and the one that does not can move further and faster than the two that did. That arithmetic is what position sizing exists to answer, and no pattern improves it.
What this number is not
It is not our record, it is not a forecast for any particular chart, and it is not the rate at which the measured objective is reached — that is always lower. It is a conservative reading of how often a completed inverse head and shoulders kept going before it went back through the level that invalidates it. Base rates move with the market, the timeframe and the exact definition used, and every one of those varies.
What failure looks like
The classic failure is a right shoulder that keeps going. It forms, looks correct, and then continues past the head — at which point every element of the pattern is gone at once. The other failure is the neckline break that cannot hold, which matters here more than elsewhere because this is the shape the largest number of people are watching for.
- The right shoulder forms on heavier volume than the head did.
- The neckline slopes steeply downward.
- The right shoulder is materially deeper than the left one.

Seeing it on a live chart
Draw the neckline before the right shoulder is finished, and then leave it alone. A neckline adjusted after the fact will always be the line that made the break look best, and the discipline of drawing it early is what makes the reading comparable from one chart to the next.
